Which of the following violates the Aufbau principle?
kondor19780726 [428]

E and B

Explanation:

The last option violates Aufbau's principle.

Aufbau's principle states that "the sublevels with lower energies are filled up before those with higher energies."

This implies that orbitals are not filled based on numerical order but on their energy levels.

The order is as follows;

   1s 2s 2p 3s 3p 4s 3d  e.t.c

In B, the 3s was not filled before jumping to 3p

In E, 3p was not filled before jumping to 3d and 3d was not even the next orbital.
